18 Seconds: A man with a Scottish accent (protagonist?) starts talking but background is still red.
19 Seconds: It switches to a plain white background.
23-40 Seconds: Confusing close up shot of a man. We can assume the voice is his?
40-45 Seconds: The music starts which is instrumental and very upbeat, at this moment we are confused about the genre. There is a shot of a road.
45 Seconds: There is a shot of a street which presumably has been sped up to confuse viewers, in addition to the music, it doesn't really give the audience a chance to think.
54 Seconds: Just a shot of the road when the first title is introduced. It is a simple, Sans Serif font which is white and bold. There are no capitals. The order is, the production companies and then the name of the actors.
1.04-1.10 Seconds: A shot in a forest. The title shot in the forest is established which is in red and stands out.
1.10 Seconds: Back to city road shot.
120 Seconds: Back to the forest which makes the audience wonder what the significance of the forest actually is.
126 Seconds: Another road city shot.
140 Seconds: Shot inside a house of a man going up a spiral staircase. Looks confusing.
The opening sequence establishes the three main settings: the city, the forest and inside this house. The genre is unclear but we can presume it is a psychological kind of thing by the type of shots but also something more upbeat due to the music.
